My dads f150 shuts off intermitiatly while driving it. he has to pull over and wait about 5 minutes until it restarts again. We have tried replacing the fuel filter, still shuts off! Some one pointed out the coil!? But after reading some of the previous posting, Im thinking that it might be the switch. It might be bad, shorting out and shutting down the truck? any ideas or suggestions?

 

Had the same exact problem on a 79 Bronco. After changing the ignition switch and coil, I changed the distributor, which fixed the problem.

Kewl! thanks for the info. I dont think that my dad has replaced the distributer. I know that he has replaced the fuel pump in addition to the fuel filter. thanks again, I'll have my dad look into that!

 

 

I have the same problem with my 2002 f150, and am looking for the root cause as well, I guess an 86 would not have near the same electronics

 

Welcome to FTE PERI97.

You should start a new thread, since the original post is referring to an 86 and the thread is 14 years old.

Do you have a SES light on?

 

Dash is blank with no power, here is the hitch, I pulled and replaced the PCM module and the truck fired up without hesitation. I can live with having to do that for a while but it is unnerving to have the truck shut down with 0 notice. Throatle body was just cleaned, and all starter/battery connections cleaned and protected. Brand new PCM relay. What does this module do to reset for start up?
